Are you ready, Maggots?!? Slipknot have just announced that they're bringing Knotfest back to the States for an extravaganza set to take place Oct. 24-26 in San Bernardino, Calif. The masked mavericks will headline two nights of the event, with a stellar lineup of acts filling out the rest of the the three-day bill.

The Knotfest announcement was made this evening from the stage at the San Bernardino kickoff of this year's Rockstar Energy Drink Mayhem Festival.

But it doesn't end there. The Saturday and Sunday lineups will also feature Of Mice & Men, Black Label Society, Testament, In This Moment, Hatebreed, Hellyeah, the reunited Atreyu and much more. See the current list of bands below. The Friday night festivities will serve as a pre-party bash for fans who purchase VIP or camping packages.

Also, if it wasn't clear that Slipknot are nearly done with their new album from Corey Taylor's recent interview with 'Loudwire NIghts' host Full Metal Jackie, here's some more weight to back it up. Fans who purchase tickets to Knotfest will receive a digital copy of the band's new disc when it's eventually released.

The San Bernardino event follows the announcement of Knotfest Japan, which will feature Korn, Limp Bizkit, Lamb of God, Five Finger Death Punch and more.

"Knotfest is a chance for Slipknot to bring the sensory-overload of a wild European festival -- and now we're coming for you, California,” says Slipknot percussionist Shawn "Clown" Crahan. "Playing two different sets over two nights at one location is a new experience in the history of this band. This year's Knotfests in the U.S. and Japan are going to be on another level."

Early bird discounted tickets, as well as camping packages, for Knotfest at the San Manuel Amphitheater & Campgrounds in San Bernardino go on sale Monday, July 7, at 8AM PT / 11AM ET, with VIP packages available starting Wednesday, July 9.
